4 Claims.

The present invention relates to an apparatus for coating a cementitious material in selected form and arrangement on a facing which is to be used in the fabrication of a unit from which shoulder pad blanks are to be formed and with. the facing produced therewith.

In our co-pending application for an Apparatus for and method of fabricating a shoulder pad blank, filed concurrently herewith, Ser. No. 524,278, and now Patent No. 2,389,934, and application Ser. No. 625,936, filed October 31, 1945, which is a division thereof, the fabricated unit concerned therewith and from which complemental shoulder pad blanks are formed comprises a filler interspaoed between two facings, one of which has arranged thereon a coating of cementitious material such as a glue or an adhesive by means of which the coated facing is secured to the other facing.

The present invention is concerned with an apparatus that may be used to coat a facing that may be fabricated by the apparatus and with the method described by us in that co-pending application.

Other objects, advantages and uses of the pres- I ent invention will be clear from the following description and the drawing appended thereto, in which drawing Fig. 1 is a plan View of an apparatus according ,I

to our invention, partially broken away to corn dense the drawing;

Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. 1; and

Fig. 4 is a plan view of a facing coated with cementitious material such as a glue or an adhesive with the said apparatus.

Referring now to the drawing, in the housing It between the sides l2 and [4 thereof, we support the feeding platform 16, above which the sides extend to form guides for the facing l8 as it is fed through the apparatus to form thereon the coatings of glue or other adhesive in the arrangement and form contemplated.

It will be understood that the facing l8 which is used in fabricating the unit is of fixed selected dimensions and therefore the sides or guides Hi are spaced apart to correspond in dimension to and accommodate such a facing which is to be fed through the apparatus.

As pointed out in our said co-pending application, the facing 18 that is used with said apparatus is preferably rectangular or square in shape so that when it is severed along the diagonal 2t! (Fig. 4), complemental halves 22 and 24 of equal size and shape will be thereby formed.

It is desired, as stated in said co-pending application, to provide a cementitious coating on the overlapping edges 26 and 21 around the pe riphery of the inside expanse of the facing which is to cover the filler of the fabricated unit from which the complemental shoulder pad blanks are to be formed, so that the cementitious coating will surround the filler at the periphery thereof.

In operation, the facing I8 is fed onto the platform it at the entrance to the apparatus, generally indicated by the reference character 28, and is fed onto the coating means, illustrated by the rotated wheels 30, secured to the shaft 32, as by the collars 34 and set screws 35.

The shaft 32 is secured in the sides 12 and it and held therebetween, as by collars 38, above the container M and is driven by the pulley Ail and belt 42 connected to a motor drive (not shown) to cause rotation of the glueing wheels 33 in the container at, in which a suitable cement, glue or adhesive it is carried. It will of course be understood that the shaft 32 and the wheels 30 carried thereby are positioned above the container 44 so that the wheels 39 will not be completely immersed in the cementitious material Z6 as they are rotated by the shaft.

The facing 13, if desired, as it is fed on the platform, may be held away therefrom by any suitable means such as spring Wires, which may be seated in the platform. For reasons that will become apparent from the description, the fac ing I8 is first fed into the apparatus between the sides 12 and M with the edge 50 leading.

Extending upwardly a short distance from the platform, through the spaced slots 52, we provide preferably a double feeding means for the facing, comprising spaced parallel driven shaft-s 5 3 on each of which are secured a plurality of spaced ratchet wheels 56. For reasons that will also be more apparent from the further description, the ratchet type wheels 56 are not arranged in linear alignment with the coating wheels 3b.

We have found that a comparatively fine pointed tooth 58 on the ratchet type wheel serves to very satisfactorily engage the coarsely Woven material constituting the conventional facing l8, preferably used in the fabrication of the shoulder pad blank concerned herewith.

Each shaft 54 is driven through the pulley 58 connected thereto by means of the belt E52 connected to a motor drive (not shown).

In order to direct and hold facing it against the perimeters of the wheels 30 so that it will 3 be satisfactorily coated thereby, the ratchet type wheels 56 feed the facing l8 under the rollers 64, secured to the shaft 86 fixed for rotation in the sides [2 and M.

A roller 64 preferably is positioned on each side of a coating wheel 30. Each roller is positioned relatively to the corresponding icoating wheel with its lower peripheral surface at a level lower than that of the upper peripheral surface of the coating wheel so that the facing, as it :is

fed, positively bears against thewperimeter of the coating wheel 30.

This insures that the cement, glue or adhesive, which adheres to the perimeterzofithe wheefifl as it is rotated into and out"-ofthe' cementitious material 46 in the container fl will be'adequately and uniformly coatedbn thefacing.

The outer coating wheels 30 adjacent the sides 22 and [4 form the lines of coating 68fon the overlapping edges 26 when the leading edge 50 is fed through the-apparatus. 5It-W1 111b8'16C0gnized that. the "width? of the ilines =of coating-will correspond to the. thicknessof the wheel perimeters and can be selected: accordingly.

We preferably provide axthird intermediate coating wheel 38, 'spacedbetweeii the wheels. adjacent the sides of ltheapparatus' so that ascentral line of coating. lllsis'concurremaly formed on the facing, for the purposes which we shall hereinafter describe.

As the thus coated facingiis' fed from the coat ing wheels 39 it rides on ther members l2zextending up fromand. along the apron-14' at..the exit to the apparatus, generallyfindi'cated by the reference character =16.

These fingerswhich are preferably positioned between a pair of adjacent coating wheels, hold the coated 'portionsof the. facing from contact with the apron; so thattthe:apron' 'willnot 'be smeared with the cement, glue; or..xadh'esivei.and the coating thereby damaged. "These. fingers further enable the operatorof the. apparatus to pick up the coated facing for the next operation.

In order to providekthef. lines of: coatings 18 adjacent the two otherfacingedges. 2.1,upon removing the facingnowucoatedawiththe lines'68 and 18, it is-again fed :into'. theapparatus with the edge 82 leading.

The side coating wheels30 now coat the. facing with the lines I8 of cement; 'glue or. adhesive and the intermediate wheel nowicoats it with the intermediate line 84.

During this operation the ratchetqtype wheels 56 not only feed the coated facing. through the apparatus but concurrentlyliholditsaway from the platform l6 sothat'the coatings will not be disturbed, the fine teeth 58 of the ratchet type wheels having relatively little-effect on'ithe now,

transversely positioned coatings Stand 10.

The fingers 12, it will also be understood, hold the completely coated facing from the apron and also enable the. operator :of the apparatus to pick up the finished coated facing and place it face upward for use by the operator of the apparatus describedin our co-pending application.

While a facing with only coatings 68 and '18 on the overlapping'edgesrfl' andifl' of the facing can be satisfactorily secured to Ethetunder' facing with the :filler; there-betweemrisince.therfabricated unitis out along .the: diagonal line 20, the filler in the resulting complemental .shoulderpads would not be securely'held'because'iitwould not be anywhere cemented or sewed to a facing.

By providing the 1. intersecting, intermediate lines of coating and* 84,""weprovide'a facing .coatingwheelsv 30 may pick up and carry too much of the glue or adhesive 46 for satisfactory coating operation.

In order .to provide a wiper means, we secure the arms 88 to'the' platform H5 at the edge thereof adjacent the container 44 by means of the set screws 86.

wheel having relatively 'pointed teeth,

The arms 88 are slotted at their center to provide the wiper fingers 90 at each side of a coatil'lg wheel 30.

The set screws-88extend through the longitudinal slots 92 at the rear of the arms 88 so that they may be advanced toward the adjacent wheel 30, the wheel entering intothe slot between the fingers 90, which are thereby positioned closer to the wheel so thatwthey may scrape or wipe as excess glue or adhesive.

- It will of coursebe-understood that by spacing the wheels 30 at the sidesxof theapparatus a proper interv'alapart corresponding to the guiding sides :of. theapparatusiand the width:'of the facing fed through thesapparatuspthe liIlQSf'Of coating on the facing will be :made'to correspond to the dimensions of.- the facing-r and-filler -:to. be used in the fabricated unit.

It will now beapparent that-we have provided .an apparatus by means of which facings to be used in a fabricating apparatus," such-as described in our co-pending application, maybe quickly and relatively inexpensively coated withasatisfactory glue or adhesive,-the width of which coating may be selected-and controlled by the width of the means used inwthe apparatus concerned with here.

. Itwill be further apparent that we have provided. a facing so-coated that: there is provided therewith a shoulder-pad blank, the filler ofwhich will always be' held therein against accidental removal therefrom.
